AquaProbe FEA200 AquaProbe FEA200 extends the capability of the ABB AquaProbe flowmeter by bringing together the proven AquaProbe flow sensor with the innovative AquaMaster3 transmitter. AquaProbe has been designed, in close consultation with the water industry, as an economic and accurate alternative to full-bore metering. It comprises an electromagnetic sensing head mounted on the end of a support rod. The sensing head can be installed in existing pipelines without the need for the major excavations or alterations to pipework associated with full-bore meters. It can be fitted without interrupting the water supply and can be removed easily for periodic calibration or inspection. AquaProbe is designed for installation in existing pipelines by means of a small valved tapping. It is normally installed with the sensing head on the pipe centreline, but may be located at the critical position (the mean velocity position) a distance of 1/8 of the pipe diameter away from the wall. It provides an accurate local measurement of the water velocity and, provided the flow profile is developed fully, a good flow volume measurement. If the profile is not fully developed, a traverse of the pipe can be performed, enabling an accurate flow volume measurement to be obtained in non-ideal networks. Key features include the wide flow range with the minimum measured velocity (well below that detected by insertion turbine or DP devices), no moving parts resulting in increased reliability and reduced maintenance. The AquaProbe is ideal for permanent installation to monitor potable or clean water flow. Also through the provision of multiple tappings on the supply pipelines, AquaProbe can be used as a portable survey tool to assist in the building of an accurate network model, locate leaks and check the operation of installed full-bore meters. The high sensitivity of AquaProbe enables it to traverse the pipe to establish the flow profile and so identify hydraulic problems in complex systems or ensure maximum accuracy from an AquaProbe that has been installed in a non-ideal location. Figure 1 AquaProbe flow sensor Based on ABB-proven technology, AquaProbe is supported by the expertise of ABB, the world’s leading flow meter manufacturer with many pioneering advances in water flow metering over the last decade – for example, AquaMag™, WaterMaster™, AquaProbe™ and CalMaster™. ABB operate nationally- and internationally-accredited flow calibration facilities in the UK, Germany, USA, Australia, China and India. We also offer comprehensive, locally based before and after sale services.
